【 摘 要 】

These results are from the continuing Lattice Quantum Chromodynamics runs on BG/L. We show analyzed thermodynamics results for 6-10k trajectories ({beta} dependent), of the 32{sup 3}{chi}8 runs with the p4rhmc v2.0 QMP{_}MPI.X (semi-optimized p4 code using qmp over mpi). These jobs had a number of omitted trajectories, due to zero size and over-sized data files. For this interim report these errors were removed from the output to save space. The results also include the output of a new ''histogram.perl'' script, used to plot the gauge action < S{sub g} >= 10*(1- < plaq >)-(1- < rect >) for three values of {beta}=3.51, 3.54, 3.57. This output will be used to determine the new {beta} values that will be run to define the critical temperature. We also show a preliminary analysis on the first 5,000 trajectories of the 32{sup 3}{chi}6 runs for the milc code, using the new su3{_}rhmc{_}susc{_}eos.3g1f.qmp-bgl2 faster RHMC algorithm.
